Jain Havero, a Calian warrior from the planet of Shiva IV, was a male and served alongside the formidable warlord Aron Peacebringer during the Galactic Civil War period. This young man, full of pride, was considered one of Shiva IV's most skilled combatants by 3 ABY, however, his great skill in combat occasionally led to recklessness. In 3 ABY, while probing the mystery surrounding the city of K'avor alongside Peacebringer, Kéral Longknife, and Ygal Delois, Havero came across a band of rogue outlaws threatening Leia Organa, a Rebel commander who had been forced to land on Shiva IV. Havero and his companions repelled the attackers and saved Organa, who greatly impressed Havero, as he had rarely encountered individuals from other worlds.
The debut of Havero occurred in Star Wars 53: The Last Gift from Alderaan, a story penned by Chris Claremont and published in 1981.
